Title: Analog display
IPC: G01R13/40
Filed: 1983-02-18
Abstract: The invention relates to analog displays comprising a row, a circle or a polygon of display points and a preceding display driver for driving the display points which correspond to the signal amplitude to be displayed. Display drivers are also available as integrated circuits; display points can be, for example, light-emitting diodes. Using such analog displays, only one information item can be displayed in each case without special measures, and this only with a limited number of signal values. To extend the information content and the possible applications of the analog display with a simple display driver and simple display points, the invention provides an alternating-signal source, the frequency of which is above the resolution of the human eye and the alternating signal of which is superimposed on the input signal. The analog display optionally obtains a fine resolution by sliding transitions from one display point to the neighbour, a controllable weakening of the intensity (dimming), a thermometer display in which several display points are displayed simultaneously rather than just one, or simultaneous representation of, for example, mean value and range of fluctuation of the input signal, is possible by constructing this alternating-signal source in various ways. Figure 1 shows a typical embodiment of the analog display with alternating-signal source, which is used for generating a fine resolution by means of sliding transitions. <IMAGE>

Title: Controllable load-dependent regulator for phase-gating controlled motors
Inventor: SCHULTZ DIETER
IPC: H02P27/02
Filed: 1983-07-23
Abstract: The regulator according to the invention is constructed such that it can be coupled to various power circuits and such that the e.m.f. of the motor or the output voltage of a tachogenerator can be used as the control variable, it being possible to integrate the most important components in one circuit. The function of the regulator is essentially characterised by a square-wave voltage which is synchronous to the network AC voltage and, as a result of a special type of generation has a high-low transition at the zero cross over and a low-high transition after approximately 2 ms and, as a result of superimposition of a second voltage, produced by an RC element in conjunction with a voltage divider which is variable via a foot controller, results in a voltage which, in comparison with a measurement voltage which is stored on an RC element via a differential amplifier, generates a further square-wave voltage whose high-low edge is used via a pulse amplifier to trigger a power semiconductor, and whose low potential disconnects the acceptance of measured values.

Title: Hydraulic control valve with integrated priority valve
Inventor: MUNCKE LUDWIG DIPL ING
IPC: F15B1/027
Filed: 1983-12-29
Abstract: Disclosed is a hydraulic control valve with integrated priority valve for a pressure-regulated or load-compensated system which comprises a pressure balance, a reversing valve and a pilot valve. It serves to regulate a supply by a pressure-medium source of permanent consumers and of an accumulator, to which priority consumers are attached, in such a way that the pressure in the accumulator is constantly within a certain predetermined range and does not fall below its minimum value. The reversing valve is here arranged in a control line leading from the pilot valve to the pressure balance and can switch the permanent consumers on or off by random actuation. Here, the useful volumetric flow to the permanent consumers passes merely through the pressure balance, and the latter is dimensioned for this useful volumetric flow. In the process, the reversing valve controls the pressure balance in such a way that, in accordance with its control pressure, either pump pressure is applied to the pressure balance, this being synonymous with switched-off permanent consumers, or a certain pressure determined by the pilot valve is applied to the pressure balance, which pressure brings about a throttling or even complete blocking of the connection to the permanent consumers. This certain pressure is established by the pilot valve, to which accumulator pressure is applied, in such a way that throttling occurs which increases the pump pressure to the respective accumulator pressure so that the latter can be charged.
